This patch set attempts to optimize the parallelism of SMC-R connections,
mainly to reduce unnecessary blocking on locks, and to fix exceptions that
occur after thoses optimization.
D. Wythe (10):
net/smc: Fix potential panic dues to unprotected
smc_llc_srv_add_link()
net/smc: fix application data exception
net/smc: fix SMC_CLC_DECL_ERR_REGRMB without smc_server_lgr_pending
net/smc: remove locks smc_client_lgr_pending and
smc_server_lgr_pending
net/smc: allow confirm/delete rkey response deliver multiplex
net/smc: make SMC_LLC_FLOW_RKEY run concurrently
net/smc: llc_conf_mutex refactor, replace it with rw_semaphore
net/smc: use read semaphores to reduce unnecessary blocking in
smc_buf_create() & smcr_buf_unuse()
net/smc: reduce unnecessary blocking in smcr_lgr_reg_rmbs()
net/smc: replace mutex rmbs_lock and sndbufs_lock with rw_semaphore

Hi Jan and Wenjia,
I'm wondering whether the bug fix patches need to be put together in this series. I'm considering
sending these bug fix patches separately now, which may be better, in case that our patch
might have other problems. These bug fix patches are mainly independent, even without my other
patches, they may be triggered theoretically.
Hi D.
Wenjia and i just talked about that. For us it would be better separating the fixes and the new logic.
If the fixes are independent feel free to post them to net.
Got it, I will remove those bug fix patches in the next series and send them separately.
And thanks a lot for your test, no matter what the final test results are, I will send a new series
to separate them after your test finished.
Hi D.,
I have some troubles applying your patches.
error: sha1 information is lacking or useless (net/smc/smc_core.c).
error: could not build fake ancestor
Patch failed at 0001 optimize the parallelism of SMC-R connections
Before merging them by hand could you please send the v6 with the fixes separated and verify that you are basing on the latest net / net-next tree?
That would make it easier for us to test them.
Thank you
- Jan
Hi Jan,
Sorry to have this troubles. I'll send v6 right away.
Thanks
D. Wythe
